Definition

Ebstein’s anomaly is a rare heart defect. In a normal heart, the blood flows in from the body to the right atrium. It then goes into the right ventricle. Next, the blood travels to the lungs through the pulmonary valve. Here, it picks up fresh oxygen. The blood returns to the left atrium and goes into the left ventricle. The blood moves out to the rest of the body.

This defect occurs when the tricuspid valve develops lower than normal in the right ventricle. Also, the valve does not open and close normally. This allows blood to leak in the wrong direction. Ebstein’s anomaly can be mild to severe.

This is a congenital defect. This means that the heart forms incorrectly when the baby is developing in the womb. The baby is born with the condition. It is not known why the heart develops this way in some babies.
